k8s helm方式部署夜莺监控系统
一、夜莺介绍
Nightingale | 夜莺监控，一款先进的开源云原生监控分析系统，采用 All-In-One 的设计，集数据采集、可视化、监控告警、数据分析于一体，与云原生生态紧密集成，提供开箱即用的企业级监控分析和告警能力。于 2022 年 5 月 11 日，捐赠予中国计算机学会开源发展委员会(CCF ODC)，为 CCF ODC 成立后接受捐赠的首个开源项目。
特性:

二、安装部署openebs存储
克隆夜莺github项目到本地
git clone https://github.com/flashcatcloud/n9e-helm.git
安装openebs存储
openebs安装部署参考文档：https://blog.mafeifan.com/DevOps/K8s/k8s-%E5%9F%BA%E7%A1%80-%E5%AE%89%E8%A3%85OpenEBS.html#local-pv
kubectl apply -f https://openebs.github.io/charts/openebs-operator.yaml
kubectl patch storageclass openebs-hostpath -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}' #设置openebs-hostpath为默认存储类
[root@sealyun-k8s-master-01 ~]# kubectl get pod -n openebs NAME READY STATUS RESTARTS AGE openebs-localpv-provisioner-6994cf5dd9-ct9ld 1/1 Running 7 20d openebs-ndm-cluster-exporter-84bb5fc764-rf7jr 1/1 Running 3 20d openebs-ndm-ksccz 1/1 Running 2 20d openebs-ndm-mtrds 1/1 Running 2 20d openebs-ndm-node-exporter-6sjh2 1/1 Running 3 20d openebs-ndm-node-exporter-7cvxl 1/1 Running 4 20d openebs-ndm-operator-5f8578c994-wds88 1/1 Running 3 20d [root@sealyun-k8s-master-01 ~]# kubectl get sc -n openebs NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE openebs-device openebs.io/local Delete WaitForFirstConsumer false 20d openebs-hostpath (default) openebs.io/local Delete WaitForFirstConsumer false 20d [root@sealyun-k8s-master-01 ~]# [root@sealyun-k8s-master-01 ~]#
三、通过helm安装部署夜莺监控系统
[root@sealyun-k8s-master-01 ~]# helm install nightingale ./n9e-helm -n n9e --create-namespace NAME: nightingale LAST DEPLOYED: Fri Sep 30 14:25:54 2022 NAMESPACE: n9e STATUS: deployed REVISION: 1 TEST SUITE: None NOTES: Please wait for several minutes for nightingale deployment to complete. Then you should be able to visit the nightingale web at http://hello.n9e.info For more details, please visit https://github.com/flashcat/n9e-helm [root@sealyun-k8s-master-01 ~]# [root@sealyun-k8s-master-01 ~]# [root@sealyun-k8s-master-01 ~]# [root@sealyun-k8s-master-01 ~]# kubectl get pod -n n9e NAME READY STATUS RESTARTS AGE nightingale-categraf-4vzcp 1/1 Running 84 24h nightingale-categraf-9qzlw 1/1 Running 85 24h nightingale-categraf-f6shc 1/1 Running 86 24h nightingale-categraf-jblrk 1/1 Running 86 24h nightingale-categraf-m54mr 1/1 Running 85 24h nightingale-database-0 1/1 Running 0 24h nightingale-nserver-b8d66fb69-75blt 1/1 Running 6 24h nightingale-nwebapi-679446f848-mg6b6 1/1 Running 6 24h nightingale-prometheus-0 1/1 Running 0 24h nightingale-redis-0 1/1 Running 0 24h [root@sealyun-k8s-master-01 ~]# kubectl get pvc -n n9e NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE data-nightingale-redis-0 Bound pvc-40b9f9d7-1cfa-4385-b9d8-8b461d2f8bda 1Gi RWO openebs-hostpath 24h database-data-nightingale-database-0 Bound pvc-4cafb849-a127-4097-8b4e-4495a7f98bba 4Gi RWO openebs-hostpath 24h prometheus-data-nightingale-prometheus-0 Bound pvc-41e89e56-aa6d-4f8d-95c2-80768b39b7be 4Gi RWO openebs-hostpath 24h [root@sealyun-k8s-master-01 ~]# kubectl get pv -n n9e NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE pvc-40b9f9d7-1cfa-4385-b9d8-8b461d2f8bda 1Gi RWO Delete Bound n9e/data-nightingale-redis-0 openebs-hostpath 24h pvc-41e89e56-aa6d-4f8d-95c2-80768b39b7be 4Gi RWO Delete Bound n9e/prometheus-data-nightingale-prometheus-0 openebs-hostpath 24h pvc-4cafb849-a127-4097-8b4e-4495a7f98bba 4Gi RWO Delete Bound n9e/database-data-nightingale-database-0 openebs-hostpath 24h [root@sealyun-k8s-master-01 ~]#
编辑service文件，配置NodePort，让外部访问
[root@sealyun-k8s-master-01 ~]# kubectl get svc -n n9e NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE nightingale-database ClusterIP 10.101.85.240 <none> 3306/TCP 24h nightingale-nserver ClusterIP 10.107.203.36 <none> 80/TCP 24h nightingale-nwebapi ClusterIP 10.111.55.177 <none> 80/TCP 24h nightingale-prometheus ClusterIP 10.99.128.168 <none> 9090/TCP 24h nightingale-redis ClusterIP 10.108.49.114 <none> 6379/TCP 24h [root@sealyun-k8s-master-01 ~]# [root@sealyun-k8s-master-01 ~]# [root@sealyun-k8s-master-01 ~]# [root@sealyun-k8s-master-01 ~]# kubectl edit svc -n n9e nightingale-nwebapi # Please edit the object below. Lines beginning with a '#' will be ignored, # and an empty file will abort the edit.

卸载夜莺项目：helm uninstall nightingale -n n9e
此时可以通过NodePort端口访问夜莺监控系统
